Title: Improvements in and relating to sound producing devices
IPC: G10K7/06
Filed: 1923-07-19
Abstract: 220,436. Steven, D. M., and Steven, J. July 19, 1923. Sirens.-In a siren of the reciprocating-piston type, the piston is angularly movable with respect to the enclosing cylinder so as to vary the time, relatively to the beginning and end of a stroke, at which the sound-producing orifices come into engagement. This engagement can thus be adjusted to take place accurately at the middle of a stroke in either direction so as to give a pure note, or alternatively the orifices may only coincide at the end of a stroke in one direction in which case a note of half the pitch will be given. The rotary movement of the piston may take place automatically so as to produce changes of tone at definite time-intervals. The soundproducing orifices in the piston and in the cylinder are made in the form of helical slits of corresponding pitch. In one construction, Fig. 1, a collar g is associated through a feather e<4> and keyway e<3> with an inturned-flange on the piston head e<2>, the collar and piston being rotatable together by means of a squared head g<1> on the collar. The piston is reciprocated by fluid entering through the ports h<2>, the piston head being provided with annular grooves h<4>, h<5> which communicate with the two sides of the piston head and are connected together through a groove h<6> at the end of the forward stroke, whereby the operating fluid passes to the chamber c<2> and effects the return movement. In a modification, Fig. 3, the piston has a conical head e<2> the opposite sides of which are alternately associated with the fluid input l<1> by means of a groove j and ports j<2>, respectively. A slit j<4> permits the insertion of a screw-driver to rotate the piston e. If high-pressure fluid is employed, the cylinder e is preferably surrounded by a perforated casing n which reduces the pressure at the sounding orifices. In a further modification, the piston is a fixture and the cylinder reciprocates thereon.

Patent GB-147030-A (GB)
Title: Improved process for the production of manganese dioxide
IPC: C01G45/02
Filed: 1920-07-06
Abstract: A solution of manganese nitrate is boiled whereby manganese di-oxide is precipitated and nitric fumes are evolved.  The latter by treatment with air and water are worked up to form nitric acid.ALSO:A powdered ore containing an oxide of manganese is suspended in water or a solution of manganese sulphate or dithionate, and sulphur dioxide passed into the hot liquor, whereby manganese sulphate and dithionate are produced.  When manganic oxide Mn2O3 is present, sulphuric acid must be added.  In practice, the suspension of the ore is contained in a series of towers, three being a convenient number, and the sulphur dioxide passing from the top of the first, which is maintained at a temperature somewhat above 60 DEG  C., enters at the bottom of the second, and finally passes similarly through the third. In the two latter towers, each of which is cooler than the preceding one, both sulphate and dithionate are formed, but the dithionate in the first is almost completely decomposed to sulphate owing to the higher temperature.  After a time, the passage of the sulphur dioxide is stopped and hot air is passed until all the sulphur dioxide has been driven from the first tower and the iron dissolved as impurity from the ore has been oxidized to the ferric state.  The decomposition of any dithionate in the first tower and the oxidation of the iron is completed by the addition of a little nitric acid. The manganese sulphate from the first tower after the undissolved matter has been separated, is removed and purified as described below, while the contents of the second tower after filtration or settling is transferred to the first tower, and that in the third is similarly transferred to the second.  The last tower is filled with water and the process continued with a fresh supply of ore.  The iron, aluminium, and phosphoric acid, having been precipitated with lime and separated, the manganese sulphate solution is converted to nitrate by the addition of calcium nitrate and boiled after the removal of the precipitated calcium sulphate by filtration. Manganese dioxide is thereby precipitated, and the resulting oxides of nitrogen are passed up a series of towers in which they are converted to nitric acid by means of water and air or oxygen. Calcium nitrate for use in the above process may be obtained by neutralizing this nitric acid with lime.

Abstract: 220,629. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Weinberger, J.). Aug. 17, 1923, [Convention date]. Atmospherics, eliminating; aerials. - Certain types of atmospheric disturbances or strays are prevented from affecting wireless receivers by a method based on the assumption that the field of such disturbances is purely electric in character, with no magnetic component. Two aerials 1, 2 are employed, the. aerial 2 being responsive to electric fields, but not magnetic fields, and the current received on this aerial is adjusted in phase and combined with the current received on the other aerial 1, in such a way as to balance out the effect of electric fields. The aerial 2 may comprise a short horizontal portion. and a down lead shielded by an earthed cylinder 3 of copper gauze &c., or passing through a shielded building. The horizontal portion is not cut by the horizontal magnetic lines of a travelling wave, and the screening of the vertical lead therefore renders the whole aerial 2 irresponsive to the magnetic component of waves. The vertical aerial 1 responds to both the electric and magnetic components of the wave. The received currents are combined in a circuit 14, 15 coupled by coils 13 to phase-adjusting devices 10, 12 connected in the secondary circuits of the two aerials. The detector 16 is connected across the condenser 15. The phase of the two received currents is adjusted by turning the coil 13 in the rotary field created by the coils 10, 12, and their relative intensity is varied by adjusting the couplings 6, 7. The damping of the aerials is equalized by adjustable resistances 8.

Abstract: 166,546. Borel, J. L. A. July 17, 1920, [Convention date]. Addition to 143,890. Drawings to Specification. Spray carburettors.-The parent Specification describes means for reducing the virtual weight of the float as the engine speed increases by transmitting suction to an extension thereof. The invention cons sts in providling the float with several extensions or pistons; with one piston to which the usual float levers are attached, with pistons tending to raise the float through rods and levers; with a piston guided in the upper wall of the suction chamber and with pistons the rods of which act directly on the float and are guided at their lower ends. Holes are provided in the top of the tank or in the suction chamber to prevent suction from being transmitted to the fuel in the float chamber. Further, the carburettor may have several nozzles entering the float chamber at different levels so as to be brought into action in succession, or a single nozzle may be fed through a slot of varying shape or a number of holes. Other constructions are described in which the suction on the piston or extension can only act after a predetermined opening of the throttle valve, this being ensured either by the use of non-return, spring-flap, or dash-pot-controlled valves in the suction conduit or by controlling the conduit by a valve actuated by the throttle valve.

Title: Preparation of 3:4-dichlorbutene-1
Inventor: BELLRINGER FREDERICK JAMES
IPC: C07C17/00
Filed: 1956-06-22
Abstract: The process of the parent Specification in which butadiene 1:3 is additively chlorinated in the presence of n-butene is modified by treating the chlorination product to isomerize 3:4-dichlorbutene-1 into 1:4-dichlorbutene-2, separating the 1:4-dichlorbutene-2 from the isomerization product by distillation and reconverting the 1:4-dichlorbutene-2 into 3:4-dichlorbutene-1.  The chlorination is carried out as in the parent Specification.  Before the isomerization process any 1:4-dichlorbutene-2 produced in the chlorination step is preferably separated from the reaction product by distillation. The isomerization may be carried out by heat alone or preferably also in the presence of an isomerization catalyst such as ferric chloride, titanium chloride, zinc chloride, aluminium chloride, boron trifluoride, mixtures of these compounds, cuprous and cupric halides and other copper compounds such as carbonates, oxides or sulphides, cuprous sulphite, cuprous thiocyanate, cupric sulphate, cupric nitrate, cupric acetate, cupric phosphate, cupric selenate, cupric tartrate, cupric stearate, cupric lactate or copper metal itself.  An organic amine such as tri-n-butylamine, quinoline, a -picoline, pyridin, o-anisidine or triethanolamine may be used in combination with the copper salts.  Suitable amounts of catalyst from 0.01-5 per cent by weight of the dichlorbutene.  In the case of copper chloride/organic amine catalysts it is preferably to use between 0.1 and 1 per cent by weight of the copper chloride, and an amount of amine between about 2 and 5 times the weight of copper chloride. Temperatures up to the boiling point of the isomerization mixture are suitable for the reaction.  When a substantial amount of the 1:4-isomer has been formed the catalyst is removed and the mixture distilled, leaving behind 1:4-dichlorbutene-2.  The head product may be then isomerized and redistilled.  The recovered 1:4-dichlorbutene may be reconverted into 3:4-dichlorbutene-1 in a second isomerization step, which may be carried to completion by continually distilling the reaction mixture in the presence of the isomerization catalyst. An example is given.  Specification 798,889 is referred to.
